Child Sex Ratio UPSC relevant
The child sex ratio (CSR) is the number of females per 1,000 males in the 0–6 age group, calculated from census age returns. Because it reflects births over roughly the previous seven years, it is the census's most sensitive indicator of sex-selective practices and differential survival of girls.
ORGI publishes dedicated CSR analyses, and the indicator has declined census after census in recent decades, reaching its lowest recorded level in 2011 — a key driver of policy responses such as Beti Bachao Beti Padhao. Census 2027's child sex ratio, derived from single-year age data collected in Population Enumeration (February 2027), will show whether the post-2011 improvement in sex ratio at birth reported by sample surveys is confirmed by a full count.
